Ava Chow 947f2925d5 Merge bitcoin/bitcoin#31124: util: Remove RandAddSeedPerfmon
9bb92c0e7f util: Remove RandAddSeedPerfmon (Hodlinator)

Pull request description:

  `RegQueryValueExA(HKEY_PERFORMANCE_DATA, ...)` sometimes hangs *bitcoind.exe* on Windows during startup, at least on CI.

  We have other sources of entropy to seed randomness with on Windows, so should be alright removing this. Might resurrect if less drastic fix is found.

  Hopefully sufficient to fix #30390.

  CI debugged with temporary Windows stack trace dumping + Symbols in #30956.

Ava Chow 7640cfdd62 Merge bitcoin/bitcoin#31118: doc: replace -? with -h and -help
33a28e252a Change default help arg to `-help` and mention `-h` and `-?` as alternatives (Lőrinc)
f0130ab1a1 doc: replace `-?` with `-h` for bench_bitcoin help (Lőrinc)

Pull request description:

  The question mark is interpreted as a wildcard for any single character in Zsh (see https://www.techrepublic.com/article/globbing-wildcard-characters-with-zsh), so `bench_bitcoin -?` will not show the help message on systems using Zsh, such as macOS.

  Since `-h` provides equivalent help functionality (as defined in https://github.com/bitcoin/bitcoin/blob/master/src/common/args.cpp#L684-L693), the `benchmarking.md` documentation has been updated to ensure compatibility with macOS.

  ----

  ### -?
  > % cmake -B build -DBUILD_BENCH=ON && cmake --build build && build/src/bench/bench_bitcoin -?
  zsh: no matches found: -?

  ### -h
  > % cmake -B build -DBUILD_BENCH=ON && cmake --build build && build/src/bench/bench_bitcoin -h
  Usage:  bench_bitcoin [options]

  Based on the comments the args help default was also changed to `-help`, mentioning `-h` and `-?` (instead of `-?` being the default)

46dfbf169b refactor: Return optional of Coin in GetCoin (Lőrinc)
e31bfb26c2 refactor: Remove unrealistic simulation state (Lőrinc)

Pull request description:

  While reviewing [the removal of the unreachable combinations from the Coin cache logic](https://github.com/bitcoin/bitcoin/pull/30673#discussion_r1721727681), we've noticed that the related tests often [reflect impossible states](https://github.com/bitcoin/bitcoin/pull/30673/files#r1740154464).

  Browsing the Coin cache refactoring history revealed that migrating `bool GetCoin` to `optional<Coin> GetCoin` was [already proposed a few times before](https://github.com/bitcoin/bitcoin/pull/18746#issuecomment-842393167).

  This refactor makes certain invalid states impossible, reducing the possibility of errors and making the code easier to understand. This will let us remove test code that exercises the impossible states as well.
  The PR is done in multiple small steps, first swapping the new `optional` return value, slowly strangling out the usages of the return parameter, followed by the removal of the parameter.

  Most of the invalid test states were still kept, except for https://github.com/bitcoin/bitcoin/pull/30673/files#r1748087322, where the new design prohibits invalid usage and https://github.com/bitcoin/bitcoin/pull/30673/files#r1749350258 was just marked with a TODO, will be removed in a follow-up PR.

Pull request description:

  Last step in a chain of PRs (#26836, #28894, #28987, #29403).

  #### Detailed Description:
  The current wallet migration process performs only individual db writes. Accessing disk to
  delete all legacy records, clone and clean each address book entry for every created wallet,
  create each new descriptor (with their corresponding master key, caches and key pool), and
  also clone and delete each transaction that requires to be transferred to a different wallet.

  This work consolidates all individual disk writes into two batch operations. One for the descriptors
  creation from the legacy data and a second one for the execution of the migration process itself.
  Efficiently dumping all the information to disk at once atomically at the end of each process.

  This represent a speed up and also a consistency improvement. During migration, we either
  want to succeed or fail. No other outcomes should be accepted. We should never leave a
  partially migrated wallet on disk and request the user to manually restore the previous wallet from
  a backup (at least not if we can avoid it).

  Since the speedup depends on the storage device, benchmark results can vary significantly.
  Locally, I have seen a 15% speedup on a USB 3.2 pendrive.

  #### Note for Testers:
  The first commit introduces a benchmark for the migration process. This one can be
  cherry-picked on top of master to compare results pre and post changes.

  Please note that the benchmark setup may take some time (~70 seconds here) due to the absence
  of a batching mechanism for the address generation process (`GetNewDestination()` calls).

04e4d52420 test: add test for specifying custom pidfile via `-pid` (Sebastian Falbesoner)
b832ffe044 refactor: introduce default pid file name constant in tests (tdb3)

Pull request description:

  This small PR adds test coverage for the `-pid` command line option, which allows to overrule the pid filename (`bitcoind.pid` by default). One can specify either a relative path (within the datadir) or an absolute one; the latter is tested using `self.options.tmpdir`. Note that the functional test file `feature_init.py` so far only contained a stress test; with this new sub-test added, both the description and the test name are adapted to be more generic.

Pull request description:

  All supported operating systems ship with python 3.10 (or later), so bumping the minimum should not cause any issues. A bump will allow new code to use new python features.

  For reference:
  * https://packages.debian.org/bookworm/python3
  * https://packages.ubuntu.com/jammy/python3
  * FreeBSD 13/14 ships with 3.11
  * CentOS-like 8/9 ships with 3.11/3.12 (via `appstream`)
  * OpenSuse Tumbleweed ships with all python versions, e.g. https://software.opensuse.org/package/python312-base

  This is for Bitcoin Core 29.0 in 2025 (next year), not the soon upcoming 28.0 this fall.

525e9dcba0 Add submitSolution to BlockTemplate interface (Sjors Provoost)
47b4875ef0 Add getCoinbaseMerklePath() to Mining interface (Sjors Provoost)
63d6ad7c89 Move BlockMerkleBranch back to merkle.{h,cpp} (Sjors Provoost)

Pull request description:

  The new `BlockTemplate` interface introduced in #30440 allows for a more efficient way for a miner to submit the block solution. Instead of having the send the full block, it only needs to provide the nonce, timestamp, version fields and coinbase transaction.

  This PR introduces `submitSolution()` for that. It's currently unused.

  #29432 and https://github.com/Sjors/bitcoin/pull/48 use it to process the Stratum v2 message [SubmitSolution](https://github.com/stratum-mining/sv2-spec/blob/main/07-Template-Distribution-Protocol.md#77-submitsolution-client---server). The method should be sufficiently generic to work with alternative mining protocols (none exist that I'm aware off).

  This PR also introduces `getCoinbaseMerklePath()`, which is needed in Stratum v2 to construct the `merkle_path` field of the `NewTemplate` message (see [spec](https://github.com/stratum-mining/sv2-spec/blob/main/07-Template-Distribution-Protocol.md#72-newtemplate-server---client)). The coinbase merkle path is also used in Stratum "v1", see e.g. https://bitcoin.stackexchange.com/questions/109820/questions-on-merkle-root-hashing-for-stratum-pools

  This last function uses `BlockMerkleBranch` which was moved to the test code in #13191. The reason back then for moving it was that it was no longer used. This PR moves it back.

  This PR does not change behaviour since both methods are unused.

  <!--
  Please provide clear motivation for your patch and explain how it improves
  Bitcoin Core user experience or Bitcoin Core developer experience
  significantly:

  * Any test improvements or new tests that improve coverage are always welcome.
  * All other changes should have accompanying unit tests (see `src/test/`) or
    functional tests (see `test/`). Contributors should note which tests cover
    modified code. If no tests exist for a region of modified code, new tests
    should accompany the change.
  * Bug fixes are most welcome when they come with steps to reproduce or an
    explanation of the potential issue as well as reasoning for the way the bug
    was fixed.
  * Features are welcome, but might be rejected due to design or scope issues.
    If a feature is based on a lot of dependencies, contributors should first
    consider building the system outside of Bitcoin Core, if possible.
  * Refactoring changes are only accepted if they are required for a feature or
    bug fix or otherwise improve developer experience significantly. For example,
    most "code style" refactoring changes require a thorough explanation why they
    are useful, what downsides they have and why they *significantly* improve
    developer experience or avoid serious programming bugs. Note that code style
    is often a subjective matter. Unless they are explicitly mentioned to be
    preferred in the [developer notes](/doc/developer-notes.md), stylistic code
    changes are usually rejected.

  Bitcoin Core has a thorough review process and even the most trivial change

fa2b7d8d6b Remove redundant unterminated-logprintf tidy check (MarcoFalke)
bbbb2e43ee log: Enforce trailing newline, Remove redundant m_started_new_line (MarcoFalke)

Pull request description:

  There are many problems around missing a trailing newline while logging:

  * All log lines are currently terminated by a trailing newline. This means any runtime code trying to handle a "missing" newline is currently dead code.
  * Leaving a line unterminated is racy and can cause content corruption by mixing log lines from different sources.
  * It requires extra code like `m_started_new_line` to keep track of, which is annoying and pointless to maintain, because it is currently dead code, see https://github.com/bitcoin/bitcoin/pull/30386#discussion_r1684380835.
  * It requires a standalone `unterminated-logprintf` clang-tidy plugin, which is unmaintained (no one updated it for the new log function names), probably harder to maintain than normal C++ code (because it requires clang AST matcher knowledge), brittle (it can fail to detect issues at any time, if it goes out-of-sync, or be explicitly disabled via `NOLINT`), and annoying for devs (it is slow and intricate to run locally and thus only effectively run on CI or via the CI scripts).

  Fix all issues by enforcing the trailing newline in logs directly in the code. Then remove all the other stuff.

  This refactor does not change behavior.

Pull request description:

  Move util/pcp.cpp and util/netif.cpp to common/ because they depend on netaddress.cpp which is part of the common library. This was causing check-deps.sh script to fail as reported by _fanquake_ in https://github.com/bitcoin/bitcoin/pull/30415#issuecomment-2385475097.

  Also make CI fail when the `check-deps.sh` script fails. Previously it would output errors but not cause the job to fail (which was not intended).

940edd6ac2 test: refactor: introduce and use `TRUC_CHILD_MAX_VSIZE` constant (Sebastian Falbesoner)
c16ae71768 test: switch MiniWallet padding unit from weight to vsize (Sebastian Falbesoner)

Pull request description:

  This PR is a late follow-up for #30162, where I retrospectively consider the padding unit of choice as a mistake. The weight unit is merely a consensus rule detail and is largely irrelevant from a user's perspective w.r.t. fee-rate calculations and mempool policy rules (e.g. for package relay and TRUC limits), so there doesn't seem to be any value of using a granularity that we can't even guarantee to reach exactly anyway.

  Switch to the more natural unit of vsize instead, which simplifies both the padding implementation (no "round up to the next multiple of 4" anymore) and the current tests that take use of this padding. The rather annoying multiplications by `WITNESS_SCALE_FACTOR` can then be removed and weird-looking magic numbers like `4004` can be replaced by numbers that are more connected to actual policy limit constants from the codebase, e.g. `1001` for exceeding `TRUC_CHILD_MAX_VSIZE` by one. The second commits introduces a constant for that.

781c01f580 init: Check mempool arguments in AppInitParameterInteractions (TheCharlatan)

Pull request description:

  The for loop around the chain loading logic in `init.cpp` allows users of the GUI to retry once on failure with reindexing without having to manually set the reindex flag on startup. However this current mechanism has problems:

  * It is badly documented and has led to confusion among developers and bugs making it into master. Examples:
      * https://github.com/bitcoin/bitcoin/pull/28830/files#r1598392660
      * https://github.com/bitcoin/bitcoin/pull/30132#issuecomment-2120741121
  * It can only ever iterate once, making the choice of a for loop questionable.
  * With its large scope it is easy for re-entry bugs to sneak in. Example:
      * https://github.com/bitcoin/bitcoin/pull/28830#discussion_r1601589963

  Attempt to fix this by moving the bulk of the logic into a separate function and replacing the for loop with a simpler `if` statement.

  The diff's in this pull request are best reviewed with `--color-moved-ws=ignore-all-space --color-moved=dimmed-zebra`. The error behaviour can be tested by either manually making `LoadChainstate` return a failure, or deleting some of the block index database files.

Pull request description:

  Continues #30005. Closes #17012..

  This PR adds PCP (Port Control Protocol) from [RFC6887](https://datatracker.ietf.org/doc/html/rfc6887).  This adds, in addition to the existing IPv4 port mapping (which now uses PCP, with fallback to NAT-PMP), support for IPv6 pinholing-that is, opening a port on the firewall to make it reachable.

  PCP, like NAT-PMP is a simple UDP-based protocol, and the implementation is self-contained, so this gets rid of lthe libnatpnp dependency without adding a new one. It should otherwise be a drop-in replacement. NAT-PMP fallback is implemented so this will not make router support worse.

  For now it is disabled by default, though in the future (not in this PR) we could consider enable it by default to increase the number of connectable nodes without adding significant attack surface.

  To test:
  ```bash
  bitcoind -regtest -natpmp=1 -debug=net
  ```

  (most of the changes in this PR are, ironically, removing the libnatpmp dependency and associated build system and build docs)

Pull request description:

  I discovered that we don't write the best block to disk when trying to explain the behavior described here: https://github.com/bitcoin/bitcoin/pull/30455#discussion_r1719951882

  In the context of that test, the behavior is confusing and I think it also shows that one of the already existing tests in `wallet_assumeutxo.py` doesn't actually test what it says. It only fails because the best block isn't written and actually, the height of the backup that is loaded is at the snapshot height during backup. So it really shouldn't fail since it's past the background sync blocks already.

  I'm not sure if this is super relevant in practice though so I am first looking for concept ACKs on the `BackupWallet` code change. Either way, I think this behavior should be documented better if it is left as is and the test should be changed.

Pull request description:

  This continues the work in #30200 so that a future Stratum v2 Template Provider (see #29432) can avoid accessing node internals. It needs to know when a new block arrives in order to push new templates to connected clients.

  `waitTipChanged()` uses a new kernel notification `notifications().m_tip_block_mutex`, which this PR also introduces (a previous version used `g_best_block`).

  In order to ensure the new method works as intended, the `waitfornewblock`, `waitforblock` and `waitforblockheight` RPC methods are refactored to use it. This allows removing `RPCNotifyBlockChange`.

  There's a commit to add (direct) tests for the methods that are about to be refactored:
  - `waitfornewblock` was already implicitly tested by `feature_shutdown.py`.
  - `waitforblockheight` by `feature_coinstatsindex.py` and `example_test.py`

  This PR renames `getTipHash()` to `getTip()` and returns a `BlockRef` (renamed from `BlockKey`) so that callers can use either the height or hash.

  The later commits make trivial improvements to the `waitfor*` RPC calls (not needed for this PR).

  The `waitTipChanged()` method could probably also be used for the longpoll functionality in `getblocktemplate`, but I'm a bit reluctant to touch that.

  `RPCServer::OnStarted` no longer does anything and `RPCServer::OnStopped` merely prints a log statement. They were added in #5711 as a refactor. This PR drops them entirely.

  Finally `g_best_block` is also dropped.

  To enable both `unsigned char` and `std::byte` values, I've extracted the existing serialization to append the size & data in separate private methods to clarify that it does more than just a simple data insertion.

  There were also discussion on eliminating the operators here completely to obviate when we're serializing fixed-size collections as raw bytes, and when we're prefixing them with their size - should also be done in a separate PR.

  The added assertion just makes sure that the fuzz test is working as intended. If we're sure that the total work of the test chain is never more than minimum chain work, then we can be sure that the later assertion failure would actually mean that a bug in the headers presync logic was found.

  ### Reason

  "The toolchain from RISC Zero defines int and int32_t as different types, although they have the same width. This means that `src/compat/assumptions.h` compiles fine; however, the templated serialization code cannot accept values of type int. Fix the compilation on RISC Zero by serializing int32_t instead of int values.

  This patch will explicitly use the `int32_t` type instead of `int` to avoid errors when compiling with the risc0 toolchain. Additionally, this patch will not change any behavior on platforms where compilation was previously successful.

  Fixes #30747

Pull request description:

  Previously, when an invalid port was specified in `-rpcbind`, the `SplitHostPort()` return value in `HTTPBindAddresses()` was ignored and attempt would be made to bind to the default rpcbind port (with the host/port treated as a host).

  This rearranges port checking code in `AppInitMain()` to handle the invalid port before reaching `HTTPBindAddresses()`.  Also adds a check in `HTTPBindAddresses()` as a defensive measure for future changes.

  Adds then updates associated functional tests as well.

051ba3290e addrman, refactor: introduce user-defined type for internal nId (Martin Zumsande)

Pull request description:

  With `nIdCount` being incremented for each addr received, an attacker could cause an overflow in the past, see https://bitcoincore.org/en/2024/07/31/disclose-addrman-int-overflow/
  Even though that attack was made infeasible indirectly by addr rate-limiting (PR #22387), to be on the safe side and prevent any regressions change the `nId`s used internally to `int64_t`.
  This is being done by first introducing a user-defined type for `nId`s in the first commit, and then updating it to `int64_t` (thanks sipa for help with this!).

  Note that `nId` is only used internally, it is not part of the serialization, so `peers.dat` should not be affected by this.

  I assume that the only reason this was not done in the past is to not draw attention to this previously undisclosed issue.

Pull request description:

  This PR changes addrman's `Select` to support multiple networks and change `ThreadOpenConnections` to call it with reachable networks. It can avoid unnecessary `Select` calls and avoid exceeding the max number of tries (100), especially when turning a clearnet + Tor/I2P/CJDNS node to Tor/I2P/CJDNS. Compared to #29330, this approach is "less aggresive". It does not add a new init flag and does not impact address relay.

  I did an experiment of calling `Select` without passing a network until it finds an address from a network that compose 20% ~ 25% of the addrman (limited to 100 tries).

Pull request description:

  Fixes #20978

  If a block was pruned, `getblock` already returns a specific error: "Block not available (pruned data)".
  But if we haven't received the full block yet (e.g. in a race with block downloading after a new block was received headers-first, or during IBD) we just return an unspecific "Block not found on disk" error and log
  `ERROR: ReadBlockFromDisk: OpenBlockFile failed for FlatFilePos(nFile=-1, nPos=0) `
  which suggest something went wrong even though this is a completely normal and expected situation.

  This PR improves the error message and stops calling `ReadRawBlockFromDisk()`, when we already know from the header that the block is not available on disk.
  Similarly, it prevents all other rpcs from calling blockstorage read functions unless we expect the data to be there, so that `LogError()` will only be thrown when there is an actual file system problem.

  I'm not  completely sure if the cause is important enough to change the wording of the rpc error, that some scripts may rely on.
  If reviewers prefer it, an alternative solution would be to keep returning the current "Block not found on disk" error, but return it immediately instead of calling `ReadRawBlockFromDisk`, which would at least prevent the log error and also be an improvement in my opinion.

  result in an honest peer in IBD connecting to the AssumeUTXO node (while syncing)
  and requesting an historical block the node does not have. This behavior leads to
  an abrupt disconnection due to perceived unresponsiveness from the AssumeUTXO
  node.

  This lack of response occurs because nodes ignore `getdata` requests when they do
  not have the block data available (further discussion can be found in #30385).

  Fix this by refraining from signaling full-node service support while the
  background chain is being synced. During this period, the node will only
  signal `NODE_NETWORK_LIMITED` support. Then, full-node (`NODE_NETWORK`)
  support will be re-enabled once the background chain sync is completed.

  Thanks mzumsande for a post-#30385 convo too.

  Testing notes:
  Just cherry-pick the second commit (bb08c22) on master.
  It will fail there, due to the IBD node requesting historical blocks to the snapshot
  node - which is bad because the snapshot node will ignore the requests and
  stall + disconnect after some time.

Ava Chow 082779d606 test: Add explicit onion bind to p2p_permissions
When the bind option is replaced in the bitcoin.conf, bitcoind will
attempd to bind to the default tor listening port. If another bitcoind
is running that is already bound to that port, the bind will fail which,
since #22729, causes the test to fail.

This failure can be avoided by explicitly binding the tor port when the
bind is removed.

Pull request description:

  Add `-ipcbind` option to `bitcoin-node` to make it listen on a unix socket and accept connections from other processes. The default socket path is `<datadir>/node.sock`, but this can be customized.

  This option lets potential wallet, gui, index, and mining processes connect to the node and control it. See examples in #19460, #19461, and #30437.

  Motivation for this PR, in combination with #30510, is be able to release a bitcoin core node binary that can generate block templates for a separate Stratum v2 mining service, like the one being implemented in https://github.com/Sjors/bitcoin/pull/48, that connects over IPC.

  Other things to know about this PR:

  - While the `-ipcbind` option lets other processes to connect to the `bitcoin-node` process, the only thing they can actually do after connecting is call methods on the [`Init`](https://github.com/bitcoin/bitcoin/blob/master/src/ipc/capnp/init.capnp#L17-L20) interface which is currently very limited and doesn't do much. But PRs [#30510](https://github.com/bitcoin/bitcoin/pull/30510), [#29409](https://github.com/bitcoin/bitcoin/pull/29409), and [#10102](https://github.com/bitcoin/bitcoin/pull/10102) expand the `Init` interface to expose mining, wallet, and gui functionality respectively.

  - This PR is not needed for [#10102](https://github.com/bitcoin/bitcoin/pull/10102), which runs GUI, node, and wallet code in different processes, because [#10102](https://github.com/bitcoin/bitcoin/pull/10102) does not use unix sockets or allow outside processes to connect to existing processes. [#10102](https://github.com/bitcoin/bitcoin/pull/10102) lets parent and child processes communicate over internal socketpairs, not externally accessible sockets.

Pull request description:

  This adds a test that checks that network activity is not suspended if dumptxoutset fails in the middle of its process which is implemented with the `NetworkDisable` RAII class. I would have liked to add coverage for the `TemporaryRollback` RAII class but that seems a lot more tricky since the failure needs to happen at some point after the rollback and on the scale of our test chain here I couldn't find a way to do it yet. This was requested by pablomartin4btc here: https://github.com/bitcoin/bitcoin/pull/30808#pullrequestreview-2280450117. To test the test you can comment out the content of the destructor of `NetworkDisable`.

  It also addresses the feedback by ryanofsky to use `std::optional` instead of `std::unique_ptr` for the management of the RAII object: https://github.com/bitcoin/bitcoin/pull/30808#discussion_r1744149228

Pull request description:

  Currently, if users provide a double negated value such as '-nowallet=0' or a non-boolean

Pull request description:

  The current `rpcauth` parsing behavior is inconsistent and unintuitive (see https://github.com/bitcoin/bitcoin/pull/29141#issuecomment-1972085251 and additional details below).
  The current behavior inconsistently treats empty `rpcauth` as an error (or not) depending on the location within CLI/bitcoin.conf and the location of adjacent valid `rpcauth` params.

  Empty `rpcauth` is now consistently treated as an error and prevents bitcoind from starting.
  Continuation of the upforgrabs PR #29141.

  ### Additional details:
  Current `rpcauth` behavior is nonsensical:

   - If an empty `rpcauth` argument was specified as the last command line argument, it would cause all other `rpcauth` arguments to be ignored.
   - If an empty `rpcauth` argument was specified on the command line followed by any nonempty `rpcauth` argument, it would cause an error.
   - If an empty `rpcauth=` line was specified after non-empty rpcauth line in the config file it would cause an error.
   - If an empty `rpcauth=` line in a config file was first it would cause other rpcauth entries in the config file to be ignored, unless there were `-rpcauth` command line arguments and the last one was nonempty, in which case it would cause an error.

  New behavior is simple:
   - If an empty rpcauth config line or command line argument is used it will cause an error

  Work around this issue by ignoring this diagnostic for this include. I did attempt to just downgrade the error into a warning, but that did not seem to work. Not a huge fan of inline warning/issue suppression, but this seems like the cleanest thing to do here (and easy to backport to `28.x`).

  Can be tested with something like:
  ```bash
  docker pull debian:bookworm
  docker run -it debian:bookworm /bin/bash

c4762b0aa0 test: allow excluding func test by name and arg (Max Edwards)

Pull request description:

  While working on CI I wanted to disable some functional tests so I used the `TEST_RUNNER_EXTRA` var. The problem I had was tests that have flags such as `rpc_bind.py --ipv6` must be passed in quotes otherwise the `--ipv6` portion will be considered an argument to `test_runner.py` rather than a test name.

  This change allows proper parsing of quotes and complex values such as:

  ```shell
  TEST_RUNNER_EXTRA='--exclude "rpc_bind.py --ipv6,feature_proxy.py"'
  ```

  Update:

  While testing this it was noticed that `test_runner.py` when given `--exclude "rpc_bind.py --ipv6"` will exclude all `rpc_bind.py` tests so this PR has been updated to include a change to the test runner to only exclude the specific test if you pass an arg or exclude all tests of that name if you do not pass an arg. `--exclude rpc_bind.py` will exclude all three variants and `--exclude rpc_bind --ipv6` will only exclude the IPV6 variant.

Pull request description:

  There exist many usages of `fuzzed_data_provider` where it is evaluated directly in the function call.
  Unfortunately, [the order of evaluation of function arguments is unspecified](https://en.cppreference.com/w/cpp/language/eval_order), and a simple example shows that it can differ e.g. between clang++ and g++: https://godbolt.org/z/jooMezWWY

  When the evaluation order is not consistent, the same fuzzing/random input will produce different output, which is bad for coverage/reproducibility. This PR fixes all these cases I have found where unspecified evaluation order could be a problem.

  Finding these has been manual work; I grepped the sourcecode for these patterns, and looked at each usage individually. So there is a chance I missed some.

  * `fuzzed_data_provider`
  * `.Consume`
  * `>Consume`
  * `.rand`

  I first discovered this in https://github.com/bitcoin/bitcoin/pull/29013#discussion_r1420236394. Note that there is a possibility that due to this fix the evaluation order is now different in many cases than when the fuzzing corpus has been created. If that is the case, the fuzzing corpus will have worse coverage than before.

  Update: In list-initialization the order of evaluation is well defined, so e.g. usages in `initializer_list` or constructors that use `{...}` is ok.

  Refactors the code a bunch, and adds `--poolnum` / `--poolid` options so that signers can tag their coinbases in a way that explorers can recognise (see also https://github.com/bitcoin-data/mining-pools/pull/82 and https://github.com/mempool/mempool/issues/2903).

  The refactoring in particular helps enable the "try using inquisition's getblocktemplate, and if that doesn't work fall back to core's getblocktemplate" logic, as described/implemented in https://github.com/bitcoin-inquisition/bitcoin/pull/7

6eeb188d40 test: adds seednode functional tests (Sergi Delgado Segura)
3270f0adad net: Favor peers from addrman over fetching seednodes (Sergi Delgado Segura)

Pull request description:

  This is a follow-up of #28016 motivated by https://github.com/bitcoin/bitcoin/pull/28016#pullrequestreview-1913140932 and https://github.com/bitcoin/bitcoin/pull/28016#issuecomment-1984448937.

  The current behavior of seednode fetching is pretty eager: we do it as the first step under `ThreadOpenNetworkConnections` even if some peers may be queryable from our addrman. This poses two potential issues:

  - First, if permanently set (e.g. running with seednode in a config file) we'd be signaling such seed every time we restart our node
  - Second, we will be giving the seed node way too much influence over our addrman, populating the latter with data from the former even when unnecessary

  This changes the behavior to only add seednodes to `m_addr_fetch` if our addrman is empty, or little by little after we've spent some time trying addresses from our addrman. Also, seednodes are added to `m_addr_fetch` in random order, to avoid signaling the same node in case more than one seed is added and we happen to try them over multiple restarts

c5eaae3b89 doc: Add -rpcclienttimeout=0 to loadtxoutset examples (Fabian Jahr)
598b9bba5a rpc: Don't re-enable previously disabled network after dumptxoutset (Fabian Jahr)

Pull request description:

  First, this addresses two left-over comments in #29553:

  - When running `dumptxoutset` the network gets disabled in the beginning and then re-enabled at the end. The network would be re-enabled even if the user had already disabled the network themself before running `dumptxoutset`. The network is now not re-enabled anymore since that might not be what the user wants.
  - The `-rpcclienttimeout=0` option is added to `loadtxoutset` examples in documentation

  Additionally, pablomartin4btc notified me that he found his node stuck at the invalidated height after some late testing after #29553 was merged. We could not find the actual source of the issue since his logs got lost. However, it seems likely that some kind of disruption stopped the process before the node could roll forward again. We fixed this issue for network disablement with a RAII class previously and it seems logical that this can happen the same way for the rollback part so I suggest to also fix it the same way.

  An example to reproduce the issue described above as I think it happened: Remove the `!` in the following line in `PrepareUTXOSnapshot()` to simulate an issue occurring during `GetUTXOStats()`.

  ```
  if (!maybe_stats) {
  ```

  This leaves the node in the following state on master:

  ```
  $ build/src/bitcoin-cli -rpcclienttimeout=0 -named dumptxoutset utxo-859750.dat rollback=859750
  error code: -32603
  error message:

      "branchlen": 0,
      "status": "active"
    },
  ```

  (Note that the first tip is `headers-only` and not `invalid` only because I started `dumptxoutset` before my node had fully synced to the tip. pablomartin4btc saw it as `invalid`.)

Pull request description:

  Increase the maximum number of logging categories from 32 to 64.

  We're currently using 29 of the 32 available logging categories (there are only 3 remaining). It would be good to increase the limit soon; the fourth PR to be merged that adds a new logging category will be blocked until something like this is done.

  This PR also adds a `TEST` category that uses the new range (`1ULL << 63`) in case there's a hidden assumption somewhere that the `BCLog::LogFlags` type is 32 bits. (Also added a test for this test category.) It also provides an example showing that the expression must be `1ULL << <shift>` for shift value 31 and beyond.

Pull request description:

  This adds a height parameter to the `dumptxoutset` RPC. This internalizes the workflow that was previously done by scripts: roll back the chain to the height we actually want the snapshot from, create the snapshot, roll forward to the real tip again.

  The nice thing about internalizing this functionality is that we can write tests for the code and it gives us more options to make the functionality robust. The shell scripts we have so far will be more cumbersome to maintain in the long run, especially since we will only notice later when we have broken them. I think it's safe to remove these `test_utxo_snapshots.sh` as well when we have this option in `dumptxoutset` because we have also added some good additional functional test coverage for this functionality.

Pull request description:

  Since fad2991ba0, `uint256S` has been [deprecated](https://github.com/bitcoin/bitcoin/pull/30482/commits/fad2991ba073de0bd1f12e42bf0fbaca4a265508#diff-800776e2dda39116e889839f69409571a5d397de048a141da7e4003bc099e3e2R138) because it is less robust than the `base_blob::FromHex()` introduced in [the same PR](https://github.com/bitcoin/bitcoin/pull/30482). Specifically, it tries to recover from length-mismatches, recover from untrimmed whitespace, 0x-prefix and garbage at the end, instead of simply requiring exactly 64 hex-only characters. _(see also #30532)_

  This PR carves out the few `uint256S` callsites that may potentially prove a bit more controversial to change because they deal with user input and backwards incompatible behaviour change.

  The main behaviour change introduced in this PR is:
  - `-minimumchainwork` will raise an error when input is longer than 64 hex digits
  - `-assumevalid` will raise an error when input contains invalid hex characters, or when it is longer than 64 hex digits
  - test: the optional RANDOM_CTX_SEED env var will now cause tests to abort when it contains invalid hex characters, or when it is longer than 64 hex digits

  After this PR, the remaining work to remove `uint256S` completely is almost entirely mechanical and/or test related. I will open that PR once #30560 is merged because it builds on that.

fab0e834b8 bench: [refactor] iwyu (MarcoFalke)

Pull request description:

  Missing includes are problematic, because:

  * Upcoming releases of a C++ standard library implementation often minimize their internal header dependencies. For example, `_LIBCPP_REMOVE_TRANSITIVE_INCLUDES` (https://libcxx.llvm.org/DesignDocs/HeaderRemovalPolicy.html). This can lead to compile failures, which are easy to fix for developers, but may not be for users. For example, commit 138f867156 had to add missing includes to accommodate GCC 15 (and the commit had to be backported).
  * A Bitcoin Core developer removing a feature from a module and wanting to drop the now unused includes may not be able to do so without touching other unrelated files, because those files rely on the transitive includes.

  Moreover, missing or extraneous includes are problematic, because they may be confusing the code reader as to what the real dependencies are.

  Finally, extraneous includes may slow down the build.

  Fix all issues in `bench`, by applying the rule include-what-you-use (iwyu).

  Follow-up pull requests will handle the other places.

02dc45c506 seeds: Pull nodes from Luke's seeder (virtu)
7a2068a0ff seeds: Pull nodes from virtu's crawler (virtu)

Pull request description:

  This builds on #30008 and adds data [exported](https://github.com/virtu/seed-exporter) by [my crawler](https://github.com/virtu/p2p-crawler) an additional source for seed nodes. Data covers all supported network types.

  [edit: Added Luke's seeder as input as well.]

  ### Motivation
  - Further decentralizes the seed node selection process (in the long term potentially enabling an _n_-source threshold for nodes to prevent a single source from entering malicious nodes)
  - No longer need to manually curate seed node list for any network type: See last paragraph of OP in #30008. My crawler has been [discovering the handful of available cjdns nodes](https://21.ninja/reachable-nodes/nodes-by-net-type/) for around two months, all but one of which meet the reliability criteria.
  - Alignment of uptime requirements for Onion and I2P nodes with those of clearnet nodes to 50%: If I'm reading the code correctly, seeders appear to optimize for up-to-dateness by using [lower connection timeouts](https://github.com/achow101/dnsseedrs/blob/3c1a63c6723819871d76fe0fbd2155fe5a5bb171/src/crawl.rs#L349) than [Bitcoin Core](https://github.com/bitcoin/bitcoin/blob/bc87ad98543299e1990ee1994d0653df3ac70093/src/netbase.cpp#L40C27-L40C48) to maximize throughput. Since my crawler does not have the same timeliness requirements, it opts for accuracy by using generous timeouts. As a result, its data contains additional eligible Onion (and other darknet nodes), as is shown in the histogram below. Around 4500 Onion nodes are discovered so far (blue); my data adds ~6400 more (orange); ~ 1500 nodes take longer than the default 20-second Bitcoin Core timeout and won't qualify as "good".

Ava Chow 78567b052d Merge bitcoin/bitcoin#30697: Bugfix: Ensure Atomicity in Wallet Settings Updates from Chain Interface
1b41d45d46 wallet: bugfix: ensure atomicity in settings updates (ismaelsadeeq)

Pull request description:

  This PR fixes #30620.

  As outlined in the issue, creating two wallets with `load_on_startup=true` simultaneously results in only one wallet being added to the startup file.

  The current issue arises because the wallet settings update process involves:
  1. Obtaining the settings value while acquiring the settings lock.
  2. Modifying the settings value.
  3. Overwriting the settings value while acquiring the settings lock again.

  This sequence is not thread-safe. Different threads could modify the same base value simultaneously, overwriting data from other workers without realizing it.

  The PR attempts to  fix this by modifying the chain interface's `updateRwSetting` method to accept a function that will be called with the settings reference. This function will either update or delete the setting and return an enum indicating whether the settings need to be overwritten in this or not.

  Additionally, this PR introduces two new methods to the chain interface:
  - `overwriteRwSetting`: This method replaces the setting with a new value.
  Used in `VerifyWallets`
  - `deleteRwSettings`: This method completely erases a specified setting.
  This method is currently used only in `overwriteRwSetting`.

  These changes ensure that updates are race-free across all clients.

Pull request description:

  The [DNS seeder](https://github.com/achow101/dnsseedrs) that I wrote collects statistics on node reliability in the same way that sipa's seeder does, and also outputs this information in the same file format. Thus it can also be used in our fixed seeds update scripts. My seeder additionally crawls onion v3, i2p, and cjdns, so will now be able to set those fixed seeds automatically rather than curating manual lists.

  In doing this update, I've found that `makeseeds.py` is missing newer versions from the regex as well as cjdns support; both of these have been updated.

  I also noticed that the testnet fixed seeds are all manually curated and sipa's seeder does not appear to publish any testnet data. Since I am also running the seeder for testnet, I've added the commands to generate testnet fixed seeds from my seeder's data too.

  Lastly, I've updated all of the fixed seeds. However, since my seeder has not found any cjdns nodes that met the reliability criteria (possibly due to connectivity issues present in those networks), I've left the previous manual seeds for that network.

  This is a "temporary" fix until #29553 gets merged, which will remove the script entirely.

  Handle the "Block height out of range" error gracefully by checking if the node has synchronized to or beyond the required block height, otherwise without this validation the node would keep the network disabled if the user selected that option.

e85f386c4b consensus: enable BIP94 on regtest (Sjors Provoost)
dd154b0568 consensus: lower regtest nPowTargetTimespan to 144 (Sjors Provoost)

Pull request description:

  Because #30647 reduced the timewarp attack threshold from 7200s to 600s, our miner code will fail to propose a block template (on testnet4) if the last block of the previous period has a timestamp two hours in the future. This PR fixes that and also adds a test.

  The non-test changes in the last commit should be in v28, otherwise miners have to patch it themselves. If necessary I can split that out into a separate PR, but I prefer to get the tests in as well.

  In order to add the test, we activate BIP94 on regtest.

  In order for the test to run faster, we reduce its difficulty retarget period to 144, the same number that's already used for softfork activation logic. Regtest does not actually adjust its difficulty, so this change has no effect (except for `getnetworkhashps`, see commit).

  An alternative approach would be to run this test on testnet4, by hardcoding its first 2015 in the test suite. But since the timewarp mitigation is a serious candidate for a future mainnet softfork, it seems better to just deploy it on regtest.

  The next commits add a test and fix the miner code.

  The `MAX_TIMEWARP` constant is moved to `consensus.h` so both validation and miner code have access to it.

917e70a620 test: assumeutxo: check that UTXO-querying RPCs operate on snapshot chainstate (Sebastian Falbesoner)

Pull request description:

  Inspired by some manual testing I did for #28553, this PR checks that RPCs which explicitly query the UTXO set database (i.e. `gettxoutsetinfo`, `scantxoutset` and `gettxout`) operate on the snapshot chainstate as expected.

16e95bda86 Move maximum timewarp attack threshold back to 600s from 7200s (Matt Corallo)

Pull request description:

  In 6bfa26048d the testnet4 timewarp attack fix block time variation was increased from the Great Consensus Cleanup value of 600s to 7200s on the thesis that this allows miners to always create blocks with the current time. Sadly, doing so does allow for some nonzero inflation, even if not a huge amount.

  While it could be that some hardware ignores the timestamp provided to it over Stratum and forces the block header timestamp to the current time, I'm not aware of any such hardware, and it would also likely suffer from random invalid blocks due to relying on NTP anyway, making its existence highly unlikely.

  This leaves the only concern being pools, but most of those rely on work generated by Bitcoin Core (in one way or another, though when spy mining possibly not), and it seems likely that they will also not suffer any lost work. While its possible that a pool does generate invalid work due to spy mining or otherwise custom logic, it seems unlikely that a substantial portion of hashrate would do so, making the difference somewhat academic (any pool that screws this up will only do so once and the network would come out just fine).

  Further, while we may end up deciding these assumptions were invalid and we should instead use 7200s, it seems prudent to try with the value we "want" on testnet4, giving us the ability to learn if the compatibility concerns are an issue before we go to mainnet.

Pull request description:

  Coming from #29073.

  Applied ryanofsky suggested changes on https://github.com/bitcoin/bitcoin/issues/29073#issuecomment-2274237242 with few modifications coming from https://github.com/bitcoin/bitcoin/pull/18338#issuecomment-605060348.

  The only point I did not tackle from https://github.com/bitcoin/bitcoin/pull/18338#issuecomment-605060348 is:

  > * Move log print and flush out of ReleaseWallet into CWallet destructor

  Because it would mean every `CWallet` object would flush data to disk during destruction. Which is not necessary for wallet tool utilities and unit tests.

Pull request description:

  This adds snapshot parameters for mainnet block 840,000.

  You can generate the snapshot yourself using `./contrib/devtools/utxo_snapshot.sh` or download my torrent:
  * torrent: `magnet:?xt=urn:btih:596c26cc709e213fdfec997183ff67067241440c&dn=utxo-840000.dat&tr=udp%3A%2F%2Ftracker.bitcoin.sprovoost.nl%3A6969`

  It would be a good idea to test:
  1. That you can produce the same snapshot file, sha256 sum:
